Online Lee Valley Mirka 3″ × 4″ Soft Grip-Faced Interface Pad

Used with a Mirka 3″ × 4″ orbital sander or for hand sanding, this interface pad works with hook-and-loop abrasives for use on rounded surfaces and contours.

Made of a pliable but highly durable cushioning material, the 0.28″ thick pad is placed between the backing pad and the abrasive to help produce a more even result.

When used with a dust-collection system, the 33-hole pattern permits good airflow behind the abrasive, which extends its life and avoids damaging surfaces with stray grit particles.
